Developers will need to convert the old sysvinit init scripts to native systemd ones and/or review and use ones that have been provided to them and package them as per packaging guidelines which can be found here with sample scriptlet snippet which can be found here no later then beta for inclusions in the release.

How To Test

Install/update to the package that contains the new native systemd unit file.

Check if the update process happened cleanly

Check if the old sysvinit init script did get removed after install

Check if the service starts cleanly after install

check if the service stops cleanly after and install

Check if the service reloads cleanly correctly if applicable

Enable the service then restart

check if the shutdown process happened cleanly with the service enabled

check if the service started cleanly at startup

User Experience

Native systemd service configuration files are much easier to understand and configure compared to sysvinit scripts and the bootup process should get faster.

Dependencies

Depends on present of systemd being installed which is the case for Fedora 15 and onwards.

Contingency Plan

Continue to ship the old sysvinit init script.

Documentation

It's recommended that documentation is updated to reflect usage of the native systemd commands instead of service and chkconfig commands although that service and chkconfig commands will continue to work and are backwards compatible up to a certain extent.

An example usage of systemd commands usage compared to service and chkconfig ones can be found here.

Some documentation regarding starting and stopping some service might need to be updated since the sysvinit init script might have been split into more then one service files. Note that should not be the general case.

Release Notes

There shouldn't be anything we need to specifically say other than highlighting the change.
